// DOCUMENT REFERENCE

Document succession is verified

AN960 is canceled and its named successor is NAS1149. The document relationship does not establish a complete-part conversion.

// PART-NUMBER REVIEW

Do not convert the prefix alone

A full washer designation carries more information than the document family. Size, thickness, material and finish must survive a conversion. Use the actual notice table and its notes rather than inferring the new designation from a similar-looking number.

This page confirms the standard relationship; it does not publish unverified dash-by-dash conversion pairs.

Compare the washer function

A flat washer reference should remain separate from an internal-tooth, external-tooth or helical split lock washer. Match the required inside diameter, outside diameter and thickness as well as the material and surface treatment.
